首先,我没有创建它,我只是通过一个完整的示例使其易于理解。
您可以在此处阅读更多内容,但这仅仅是因为archive.org。
https://web.archive.org/web/20160106095540/http://designaeon.com/2012/07/read-mp3-tags-without-downloading-it/
首先,从这里下载这个库:http://getid3.sourceforge.net/
当您打开 zip 文件夹时,您会看到“getid3”。将该文件夹保存到您的工作文件夹中。
接下来,在将要运行以下脚本的工作文件夹中创建一个名为“temp”的文件夹。
基本上,它的作用是下载文件的前 64k,然后从文件中读取元数据。
我喜欢一个简单的例子。我希望这会有所帮助。
<?php
require_once("getid3/getid3.php");
$url_media = "http://example.com/myfile.mp3"
$a=getfileinfo($url_media);

echo $a['tags']['id3v2']['artist'][0] . "\n";
echo $a['tags']['id3v2']['title'][0] . "\n";
echo $a['tags']['id3v2']['year'][0] . "\n";
echo $a['tags']['id3v2']['year'][0] . "\n";
echo "\n-----------------\n";
//print_r($a['tags']['id3v2']['album']);
